Pennsylvania is often referred to the mushroom capital of the world. 63% of the United States white mushroom crop is grown in this state. What is better than stuffed mushrooms for an appetizer or even stuffed portabellas as a main entree? This tasty ground beef filling is chock full of hidden veggies and lots of flavor. I will often triple this recipe, stuff, and bake the mushrooms. They then can be frozen in a single layer on a cookie sheet. When totally frozen; vacuum pack in bags and return to the freezer. In need of a quick meal–defrost and heat.
